Jr., a'lcitiL/.eufof the United States, residing at- ,-165,- North Royal street, Jackson, Tentype, in which ycont-act between ,the drlnker`s nessee,have invented a certain new and useful improvement 1n" Samtary D'rmkmgfjv l ounta1ns,ot` which the following isa full,

cllea and exact description.

Mymvention 1s an improvement 1n drinking.: fountains 'of the A"so-calledsanitary `lips and any part` of thefountain is impossible and in which any water with which a user`s lipsmay have come in contact, is automatically 'removed by theflow of 'ater bet'ore subsequent use, and/my invention relates niore particularly to drinking fountaiiis especially adapted to use on railway t/rains and similar places where itl is essential that the consumptionof water be reduced to a mmunum.

To this end the'primary objects of my in- 5 ywhich water may be supplied in no greater 25 quantities than necessary andonly at. the time ofuse; and the 'design of a bubblingy fountain which, while perfectly sanitary, shall use a minimum quantity of water.

Fui-ther objects of lny invention will hereinafter appear in the specification and be pointed outy in the appended claims.

ln the accompanyimgr drawings, Figure l is a view of the assembled device, showing the water tank, the cooling;r coils and the fountain head; Fig. 2 is a view of thc fountain head on approximately full scale, showing` the drain pipe, valve and valve stem in elevation and thc remaining parts in central, vertical cross section; and Fig. l is a perspective. also on approximately full scale, of the rear portion ot the fountain head cover, showing the manner otl mountinpr said cover.

As stated above, my invention is especially adapted for use on railway cars where it is, ot' course, inconvenient to supply the large quantities ot' water wasted by constantly flowing drinking fountains, and it in such a location thatI l have chosen to illustrate it.

A represents the aisle ot a car, l a partition between such aisle and a compartment C, and l) is the drinking fountain proper located in the car aisle. in the compartment C, supported on a shi-lt' lt. are located the water tank 5 and thel ice tank t. The water tank 5 has a filling cap 7 and a pipe 8 leading to it from any suitable source of compressed yair. Through ther valve 9, Ythe air admitted to the tank 5 may be regulated to give the proper pressure on thewater in the system. The water on leaving the tanky is passed up through coil 10 Surrounded by ice in the tank 6 and from there passes' toy the rfountain headD throujh the pipe 11.

T he fountain head is shown in section in I `ig. 2. lVater is admitted throughthe valve chamber V, the port of which 1S controlled by the valve 12 which is normally forced into its seat. by the spring 13. The valve steln'14 extends upwardly and ends in a horizont-.1l arm 15 in the path of a lug 17 on the hinged cover y153. After entering through the valve chamber V the 'Water passes upwardly through the induction pipe 1t) into chamber 2(1). The chamber 2O has conical, upwardly daring side walls 21 which end in an interiorly dependino' lip 22 which overhangs the inner surface ofa bowl shaped member 23 supported by three' or more legs 2l resting on the walls-21. Pro- 'jectina from the bottom of the bowl 23 is a nib 25. The water rising through the passage between the walls of the chamber 20-k and the'rbowl 23 isl deflected downward `by the lip 22 and. flowing down the bowlj23, strikes the nib and boils or bubbles-"thus forming what is known as a bubbling fountain. The, unconsumed excess of water passes over the exterior of the dependingr lip 22 into the outer bowl 2G from which it escapes through discharge openings 27 into the escape pipe 28.

In order to exclude dust and germs from the parts of the fountain while not In use, I provide a cover 18 hinged at 2S) on a bolt 30 held in ears 3l projecting from the outside bowl 26. Around the bolt 3() and bearing at one end on a lug 32 formed on 011e ear 31 and at the other end against the cover 18 and tending1r to close it, is a spring 33.

The manner of operation of my device is apparent. A person desiring to drink will raise the cover 18 by means of the handle 31. lVhen the cover is raised the lug 17 will contact with the horizontal arm 15 of the va`lve stem 14. will, as shown in dotted lines in Fig. 2, raise the valve 12 from its seat admitting water 4through thc induction pipe 1t) to the chum- Further movement of the co ve1 Y per edge of duction pipe, a stem for-said valve, a horizontal arm on said stem, a lug on the cover ,inposition to contact with said horizontal arm when Athe cover is raised to raise the valve stem, and a spring for returning the valve to sition when said lug is out of contact with said horizontal arm. Y.

2. In a fountain head, an induction pipe, afconicalcliamber into which said induction pipe discharges, a bowl supported within .slid chamber and n nib in the bottom of said bowl.

3. In a. fountain head, an induction pipe, a conical chamber into which said induction pipe discharges, a depending lip on the upper edge of said chamber, and an imperferate bowl supported within said chamber and under said lip,

4. In a fountain head, an induction pipe, aconical chamber into which said induction pipe discharges, a depending lip on the upsaid chamber, a -bowl su ported within said chamber and under said ip, and a nib in the bottom of said bowl.

5. ,In a fountain head, an induction pipe, a cnical'chamber into which said induction pipe. discharges a depending lip on the gupper edge ofsai chamber, a bowl supported within said chamber and under said lip, a nih in the bottom of said bowl and an outer discharge bowl surrounding the conical chamber and spaced therefrom.

G. In a fountain head, an induction pipe, a valve in said pipe, a conical chamber. into the bottom of which said induction pipe discharges, a depending lip on the upper edge of said chamber, an imperforate bowl supported within said chamber under said4 lip,

:i hinged cover and means on said cover for opening said valve when the cover is raised.

7.' In a fountain head, an induction pipe, a conical chamber into which said pipe discharges, a. depending lip on the upper edge of said chamber, a bowl supported within said chamber and under said lip, and-an orerfiow bowl surrounding said chamber.

8. In a fountain head, an induction-pipe, a valve j'n said pipe, a conical chamber into which said induction pipe discharges, a depending lip on the upper edge ot said chamher, a bowl supported within said chamber under said lip, an outer discharge bowl surrounding said chamber and spaced thcrcfroni, a hinged cover, and means on said cover for actuating said valve.`

S). In a fountain head, a, bowl, means for discharging water into said bowl at all points of its circumference, means at the ccnterl of the bowl for deflecting the water upward, and a discharge bowl surrounding said first mentioned irstbowl.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses. J NO. L. WILLIAMS, J n.
